SPINDLE.

Original application filed April 6, 1925, Serial No. 20,890. Divided and application filed November 30, 1925, Serial No. 72,088. Divided and this application filed May 17, 1926. Serial No. 109,622.

This application is a division of my spindle, and a nut 16, as shown in Fig. 2. pending application Serial No. 72,0 88 filed The journal is also provided with a disk 17 November 30, 1925, which. is a divlsion of to be engaged by a brake, but this may be my co-pending application Serial No. 20,890. omitted if desired.

The other end of the spindle is provided 60 The invent-ion relates to gelatin band spinwith a longitudinal bore 18 and a transverse dles for hectograph machines and its object slot 19 extending through its end. The is to provide a novel and improved spindle jour al 20 i t d i a b i 21 i 3 adapted to be securely mounted upon a conconveyor chain and it has a projection 22 10 veyor to hold the band at desired tension which extends into the bore 18. A pin 23 65 while it, is being used. extends transversely through the projection A further object of the invention is to 22 and is positioned in the slot 19, as shown mount the spindle upon the conveyor chalns in Fig. 3. The band 24 may be secured on so that they cannot be readily detached and the spindle by any suitable means.

Other disadvantages will result enlarged circular recess 7 The ournal 8 from improper or insecure mounting of a for this end of the spindle has a bearing 9 spindle as well as from the use of a roll in one of the conveyor chains 10 and it is which is not standard as to size and otherprovided with an end projection 11 recwise for the machine and which may be of 40 tangular in shape and terminatlng in an eninferior quality. Therefore it is important larged circular head 12. The slot 6 and the that the spindle should be mounted securely recess 7 extend entirely through the spindle and in a relatively rigid manner upon the 5, the slot being substantially rectangular conveyor chains so that it will be constantly in shape and the recess being substantially held in proper position while the roll is in 45 circular in shape. The projection 11' is use. The spindle is engaged with the joursubstantially rectangular in shape and the nal projections by first engaging the bore 18 head 12 is substantially circular in shape with the projection 22 and the transverse slot to fit snugly in the slot and recess 6, 7. A 19 with the pin 23 by an endwise movement bolt 13 passes transversely through the spinof the spindle; and then the slot and recess 50 dle and the projection 11 to secure the spin- 6, 7 at the other end of the spindle are endle rigidly to the journal, and this bolt has gaged with the projection and head 11, 12 by an enlarged head 14 which is flattened and a sidewise movement. The bolt 13 is then fitted snugly against the periphery of the inserted and secured by the nut 16. Thus s indle, a washer 15 which is flattened and the spindle is rigidly and securely mounted so tted snugly against the periphery of the upon the journals against relative move- .the spindle in proper position for en ment in any direction. The projection 11 and the head 12 fit snugly in the slot 6 and the recess 7 and the bolt 13 passing through the spindle and the and securely holds these parts together. The rojection23 fits snugly in this, bore 18 and t e transverse pin 23 registers the spindle with the headed projection 11, 12 and holds gagement with said headed projection. Thus the spindle is always maintained in proper position on'the conveyor and in exact longitudinal alignment with its journals so that the spindle will revolve to unwind or-to wind the gelatin band evenly and uniformly as required. I have illustrated the invention in a form which I have found satisfactory for actual use, but I appreciate that changes may be made to meet various conditions and therefore I reserve the right .to make all changes in the form, construction and arrangement of parts as fairly fall within the scripe of the following claims.

claim 1. A gelatin roll spindle for hectograph machines having a transverse slot extending through one end'of the spindle and terminating at its inner end in a circular transverse recess.

2. A gelatin roll spindle for hectograph machines having a longitudinal bore at one end and a transverse slot intersecting said bore and extending through that end of the spindle, and a transverse slot in the other end of the spindle aligned with said first mentioned slot.

3. A gelatin roll spindle for hectograph machines having a transverse slot extending through one end of the spindle and terminating at its inner end in a circular transverse recess, a bore in the other end of the spmdle, and a transverse slot in said other end of the spindle aligned with the first mentioned slot.

4. The combination of a pair of conveyor chains, a spindle, journals engaging the chains and carrying said spindle, one of said journals having a rectangular projection and a circular head on the outer end thereof, and said spindle having at one end a rectangular slot to receive said projection and a circular recess to receive said head, and means for securing the spindle to said projection.

5. The combination of a spindle having at one end a slot terminating in a recess and having at its other end a bore and an inprojection 11 rigidly v bolt of the spindle,

reeaoee tersecting slot aligned with said first mentioned' slot, and a pair of journals, one of said journals having a projection and a head to engage the slot and recess at one end of the spindle and having a projection and transverse pin to engage the bore and slot at the other end of the spindle, and means for securing the spindle on said projections.

6. The combination of a spindle having a slot at one end terminating in a recess, a journal having a projection and a head thereon engaging said slot and recess, and a bolt passing transversely through the spindle and said projection for securing the spindleon the journal.

7. The combination of a spindle having a slot at one end terminating in a recess, a journal having a projection and a head thereon engaging said slotand recess, and a passing transversely through the spindie and said pmjection for securin the spindle on the journal, said bolt having a flattened head shaped to fit the periphery of the spindle and being provided with a flattened washer shaped to fit the periphery of the spindle.

8. The combination of a spindle for hectograph machines having a longitudinal bore at one end and a transverse slot intersecting said bore and extending through that end a transverse slot in the other end of the spindle aligned with said first mentioned slot, a roll of gelatin band on the spindle, the inner end of said band being fastened to the spindle, and a clip at the outer end of the band. i

9. The combination of a spindle for hectographmachines having a transverse slot extending'through one end thereof and terminating at its inner end in a circular transverse recess, a roll of gelatin band on the spindle, the inner end of said band being fastened to the spindle, and a clip at the outer end of the band.

10. The combination of a spindle for hectogragh machines having a transverse slot exten ing through one end thereof and terminating at its inner end in a circular transverse recess, a bore in the other end of the spindle, a transverse slot in the other end of the spindle aligned with the first mentioned slot, a roll of gelatin band on the spindle, the inner end of said band being fastened to the-spindle, and a clip at the outer end of the band.
